In contrast, both PHMs and nonmolar specimens (including those with abnormal villous morphology) contain a maternal chromosome complement
and exhibit diffuse p57 expression in these cell types (Figure 5, B and C).
Bs in maize landrace populations may be cytologically identified as they are smaller than any of the standard chromosome complements
(As) (Longley, 1927; Randolph, 1941; Chiavarino et al., 1995).
pulchra, each have XxX2Y (male) and XxX!X2X2 (female) sex chromosome complements
. Thus, males of these two species have 47 chromosomes while females have 48.
The chromosome complement
of the 2 females (183 and 184) and 2 males (181 and 182) sampled in Goya, the type locality of C.
A karyotype study revealed a chromosome complement
Of the 26 cultures examined at passage 1, 61.5% had an abnormal chromosome complement
(62.5% in A and 60% in B).
White's book emphasised that the principles of evolution applied to individual chromosomes and the chromosome complement
just as they did to more classical morphological characters.
Unusual chromosome complement
in the brooding bivalve Lasea consanguinea.
The cells' chromosome complement
showed no abnormalities, suggesting chromosomal stability.
In this species, approximately two-thirds of the chromosomes form tetravalent associations at meiosis, as expected when the genome has doubled in size through doubling of the entire chromosome complement
(Tanaka, 1940b; Yan-Cheng & Qiu-Yun, 1989).
Silver staining (Figure 1b), as well as FISH with the 18S ribosomal genes (Figure 1c), produce signals located interstitially, close to the centromere, on one pair of chromosomes (apparently chromosome pair number 8), allowing the identification of one single pair of NOR-bearing chromosomes in the chromosome complement
. C-band positive segments (Figure 1d), more pronounced on chromosome pair number 8, were observed in pericentromeric position in all chromosomes.
The company disclosed recently it has produced multiple lines of human pluripotent stem cell lines that are able to maintain their undifferentiated state and normal chromosome complement
. In addition, the cells can be efficiently cultured in tissue culture plates without the use of feeder layers (xenofree).
